I go to the gym every Sunday as well as some quite hard physical work at Fire Cadets on Thursdays.

I'm with you. :D

Unless you are unhealthily overweight (which you aren't FC) you shouldn't be dieting at your age.

Zero is right, just being more active is the way to go

i am blessed with the best metabolism ever. i can eat whatever i want and stay the same weight.

Congrats Ferret - nothing feels better than getting rid of unwanted pounds.

I used to be somewhat overweight; not dangerously so, but far from where I should have been. Lost about 35-40 pounds last year, then built about 10-15 back in muscle. Never been in better shape in my life.

I don't bother with the whole "diet" thing, just try to eat with common sense. Avoid too much fat/grease, and go for lots of protein, fibre and vitamins. Mostly I just try to keep active though...I'm at the gym almost everyday. I tend to do more cardio than weights/resistance but I try for at least 30 minutes of each a day, alternating muscle groups.

Re-reading what I just typed makes me sound like some kind of body builder...far from it. Still eat more crap than I should and I've got the metabolism of a sloth, so even a couple days away from the gym takes its toll. Given how often I'm there I probably should be in way better shape then I actually am...but hey, I'm content to be a work in progress.

Way better than a diet and easier to maintain..

Essentially that's what I'm doing. The site allows me to keep check on the nutritional content of my food. Make sure I don't go over my fat content (59g per day apparently), try to keep my protein and fibre as high as possible whilst at the same time not going overboard on calories.

that sounds good.

The only trouble is I'm not sure if I'm going to struggle to stop. I mean, whilst I'm keeping my nutrition levels up I'm still losing weight because my overall calories that I'm allowing myself are a tiny bit lower than my body wants and to be honest, I'm still struggling to meet that quota. I think when I reach my target weight sustaining it will be the problem. Although considering that I've essentially "graduated" high school now I'll have a lot more free time, time which I could spend down the gym.
